Offering shared hosting for a Crowd coin masternode. The collateral of 1000 coins is divided into 10 "seats" of 100 coins each. I take 1% of the seat value (1 coin) up front as a setup fee and charge 5% of the masternode profit. The earnings are split evenly among the seats. If the node earns 100 coin a week, each seat receives 9.5 coins that week (taking the 5% fee into account).
